How to Remove Lead From Tap Water (and Which Filters Actually Work)
Magnus JernShort answer: you can't see, taste or smell lead, there's no safe level, and it leaches intermittently — so if your building may have old pipes, filter it. The good news: modern filtration has made this easy. A certified carbon-block faucet filter now removes 95%+ of lead (NSF/ANSI 53) for as little as ~€60/year and no plumber — you no longer need only expensive reverse osmosis or distillation. Here's who's at risk, how to test, and how to choose.
Who is at risk of lead in tap water?
More than 15% of households in North America and 5% in Europe have lead exposure above recommended levels (EPA/WHO). The main source is lead pipes and joints in older buildings, but it can also come from the municipal system (as in Flint, Michigan; a recent report also found "shocking levels" in Chicago). Buildings from the 1990s onward are low-risk unless the city supply has a problem — e.g. Thames Water (UK) recommends a filter if your house was built before the 1970s. (See tap water in London and the UK.)
What is the risk?
The biggest problem is that there is no safe level of lead, and it's especially harmful to young children and during pregnancy (neurological development), accumulating over time. It's also hard to test for: lead usually doesn't leach constantly — it comes and goes — so a clean lab result today doesn't guarantee safety tomorrow. Better safe than sorry in buildings with possible lead.
How to test your water for lead
- Home lead test kit — a quick yes/no.
- Certified laboratory test — the exact level (some water companies offer it free); the reliable option if you suspect lead pipes or solder. Remember a single test is a snapshot — lead leaches intermittently.
- Your utility's report — useful for the supply, but it can't account for your building's pipes.
How to remove lead — which filters work, and which don't
Historically, removing lead meant reverse osmosis or distillation (effective, but they strip healthy minerals and waste water/energy). Flushing the tap for 2 minutes helps but is wasteful and not fully safe. Today, even small activated carbon block filters remove 95%+ of lead, installed on the faucet without a plumber.

Method |
Removes lead? |
|---|---|
|
Certified carbon block (NSF/ANSI 53) |
✅ Yes — ~95%+ |
|
Reverse osmosis |
✅ Yes — very effective |
|
Uncertified granular-carbon jug |
⚠️ Only if certified for lead |
|
Boiling |
❌ No — concentrates lead |
|
Standard sediment filter |
❌ No |
|
Water softener |
❌ No — exchanges minerals, doesn't remove lead |
The single most important thing: look for NSF/ANSI 53 certification for lead.
The best water filters to remove lead
There are pitchers, faucet filters, gravity, under-sink and whole-house options. If your main concern is lead and common contaminants, a faucet filter is usually the best choice — e.g. the EcoPro by TAPP Water, designed and independently tested for lead removal to NSF-53. Make sure any filter is independently tested and certified. For the most thorough removal (and to also tackle nitrates and fluoride), a countertop reverse-osmosis system re-mineralises afterwards. (See how EcoPro compares to Brita, PUR, Culligan and ZeroWater.)
While you sort out a filter: use cold water for drinking/cooking, flush the tap 30 s-2 min first thing in the morning, and clean the aerator (lead particles collect there).
Conclusion
- Lead can exist anywhere, but the highest risk is old buildings with lead pipes.
- Lead above safe levels is bad for everyone, especially infants and children — no safe level.
- An affordable, certified carbon-block faucet filter (e.g. EcoPro) removes almost all lead.
- To confirm, contact a local water lab. (A 2016 Meyocks survey found 43% of Americans think their tap water is unsafe or aren't sure.)
FAQ
Do water filters remove lead? Only the right ones: a carbon block certified to NSF/ANSI 53 (~95%+), or reverse osmosis. Uncertified basic filters often don't.
Does boiling water remove lead? No — it concentrates it. Never rely on boiling.
Does a Brita-style jug remove lead? Only if that model is certified for lead — many aren't. Check for an NSF/ANSI 53 lead claim.
How do I remove lead at home? Fit a certified carbon-block faucet filter or RO, use cold water, and flush the tap after long standing periods.
Is there a safe level of lead? No — especially for children and pregnancy; reduce it as much as possible.
Do water softeners remove lead? No — they swap hardness minerals for sodium.
